Hello there,
Unfortunately, this theme does not include meta data (Author name) in posts but if you want to add you can do it your own.
The best way to make changes like this to a theme is to use a child theme, so your tweaks won’t be overwritten when updating the theme.
After making the child theme copy content.php file from main theme to child theme and edit.
Find line
the_title('<h3 class="entry-title">', '</h3>' );
and add the below code after that line
<?php the_author_posts_link(); ?>
Now you will get author name on single blog page.
Hope it helps and let me know if you require any further assistance.
